Methodology
Enzyme Linked Immunoassay
Reference Range
≤0.90 Seronegative: Suggests no prior immunological
exposure to Mycoplasma pneumoniae, result does
not rule out recent exposure and collection of test
sample prior to development of IgG. IgM
anti-Mycoplasma pneumoniae and/or culture is
recommended for determining current infection.
0.91 - 1.09 Equivocal: Immunological exposure
cannot be assessed with this value. Recommend
repeat testing in 7 - 14 days. If repeat testing
remains equivocal an alternative method should
be used. A test for IgM anti-Mycoplasma
pneumoniae antibodies may be helpful in
acute infections.
≥1.10 Seropositive: Indicates presence of IgG
antibody to Mycoplasma pneumoniae. IgM
anti-Mycoplasma pneumoniae level may be
useful if a recent infection is suspected clinically.
